The inner the sled, said shaft further provides a cylilr side of the disk surrounding the 'unctures drical portion adjacent one end thereof. a therefor upon the shaft provide enlarged or drum eccentrically mounted upon the cylin- 50 frusto-conical shaped portions 14, the purdrical portion of the shaft, braking lingers ose of which will be readily apparent. The arranged at spaced intervals upon the peiiack portion of the shaft 11 between the riphery of the drum. and converging forcompanion disks 12 and .13 is rounded cywardly througzl'iout the major portions of lindrical in cross section. their lengths, companion disks eccentric-ally and rigidly mount-ed upon the rectangular portions of the shaft and upon the opposite sides of the drum, one of the disks providing an arenate shaped cut-out portion, an operating handle carried upon the drum and protruding through the arcuate shaped cutout portion, and a retractile spring carried upon the inner side of the remaining disk and connected with the adjacent side of the drum to normally sustain the latter in a normally inactive position.

In testimony whereof I affix my signature.
